Register your new Trek

Registration is a quick and easy way to protect your new-bike investment. It provides a record of your serial number in case your bike is ever lost or stolen, and will help us get in touch with you with important product information.

Where to find the bike serial number

You can find the bike serial number on the underside of the bicycle frame, near the bottom bracket. Look for a sticker containing a barcode. This sticker will also contain a string consisting of multiple letters and numbers and beginning with WTU. This full string or characters is the bike serial number.
